It takes in average 30sec-1min to refresh the data, all the time with no "indexer --all --rotate" commands used ever. Of course, that includes the threads/posts that were deleted or edited. What is the point to store a deleted post into indexes. Not to mention that if you edit the contents of a post, the deleted keywords should not be available into search. When you rebuild the indexes, all "errors" are gone... but that occurs every 24hrs for the vB.org product.

That doesn't seem like a huge advantage to me. The deltas seem to work well enough. I don't actually know how Sphinx works, though ― you're saying that the solution posted here, rotating only the deltas, doesn't pick up edited posts? Any other disadvantages to it?
